The leaching behavior of inorganic compounds from coal into aqueous phase containing various substances, such as acids, chelating agents, and surfactants was investigated. When a powdery SS001 coal was shaken with the 0.1M HNO_3, Ca, Mg, Mn, Fe, Cu, Pb, Zn were leached out. In some elements, such as Ca, Cu, Fe and S, there was the good agreement with inorganic element contents in 12 kinds of coal and leaching of elements into aqueous phase.
